WILLIAM T. MILLER, OF IBERIA, MISSOURI.

CHURN.

Specification of Letters Patent.

Application filed August 20, 1920. Serial No. 404,735.

1'0 all whom it may concern: 7

Be it known that I, WILLIAM T. MILLER, a citizen of the United States, residing at Iberia, in the county of Miller and State of Missouri, have invented new and useful Improvements in Churns, of which the following is a specification.

This invention relates to dairy devices, particularly to churns, and has for its object the provision of a churn which is provided with means whereby it may be rotated, this means being novelly constructed and peculiarly arranged whereby to give an eccentric motion to the churn barrel within its supporting frame so as to effect an efficient churning action upon the cream dis-' posed within the device.

An important and more specific object is the provision of a churn of this character which includes an outer frame designed to be stationary, a movable inner frame provided with means whereby it may be rotated, and a novel holder carried by the movable frame and within which the churn barrel is engaged.

An additional object is the provision of a device of this character which will be simple and inexpensive in manufacture,easy to use, highly efficient in use, durable in service, and a general improvement in the art.

With the above and other objects and advantages in view, the invention consists in the details of construction to be hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in which:

Figure 1 is a front elevation of my churn.

Fig. 2 is a side elevation thereof.

Fig. 3 is a vertical longitudinal sectional view.

Fig. 4 is a cross sectional View.

Fig. 5 is a detail view of the mounting of the gearing at the top of the stationary frame.

Referring more particularly to the drawing, I have shown my device as comprising a stationary frame including a bottom base member 10 provided at its ends with supporting feet 11 and from which rise spaced upwardly converging uprights 12 connected at their upper ends by a cross piece 13. Mounted upon the cross piece at its center is a suitable bearing 14 within which is journalecl a shaft 15 carrying a bevel car 16 provided with a crank handle 17. ecured upon the underside of the cross piece 13 at its cen ter 1s a bearing member 18 within which 1S secured a stub shaft 19 upon which 18 ]ournaled a bevel pinion 2O meshing with the bevel gear 16.

Disposed within the stationary frame is a bar 21 which has its upper end curved toward the center of the frame, as clearly shown at 22, the extremity of the upper portlon being rigidly secured to the bevel pin- 1011 26 by any desired means so that the bar 21 Wlll be moved as the pinion 20 is rotated. At the lower end the bar 21 is formed with a lateral extension 23 which extends toward and past the center of the bottom cross piece 10 and which carries at the center of the cross piece 10 a depending trunnion 24 ournaled within a suitable socket 25 secured upon the bottom cross bar 10. At the juncture of the main portion of the bar 21 with ts extension 23 is located a counter-balancmg weight 26 for a purpose to be described.

The immoral 2'7 designates the barrel of the churn which is of the ordinary construction and slightly tapered toward its upper end, as clearly shown. This barrel 27 is provided with the usual closure head 28 and is provided interior-1y with cleats 29.

The barrel 27 is supported within a frame which includes a lower cross member 30 supported upon a short post 31 rising from Patented Dec. 21, 1920.

the extremity of the extension 23 of the bar 21. This cross member 30 is disposed beneath and supports the bottom of the barrel 2?, as clearly shown. Formed integrallv with the lower cross member 30 are upwardly extending strips 32 which converge upwardly and which have their upper ends connected with a sleeve 33 which is secured upon the lower end of the stub shaft 19 and prevented from disengagement therefrom by means of a suitable collar 34 on the stub shaft. Slidably mounted upon the strips 22 is a ring or hoop 35 which is engageable with catches 36 on the barrel whereby to hold the barrel stationary within the frame formed by the strip 32 and its associated parts.

In the use of the device the cream to be churned is placed within the barrel and the cover 28 secured in position in the usual manner. The operator then grasps the handle 17 and rotates the gear 16 which results in rotation of the bevel pinion 20 and rotation of the bar 21 within the stationary frame. Owing to the fact that the frame which holds the barrel 27 is secured to the extension 23 of the bar 21, it will be seen that this frame engaging the barrel and consequently the barrel itself will be rapidly rotated within the stationary frame so as to effect churning of the cream. It will be observed that the post 31 which connects the barrel supporting. frame with the movable bar 21 is eccentric with respect to the pivot point 24 and it willtherefore be obvious that the lower end of the churn will have not only a rotary actionxupon its axis but will also have'an eccentric movement which will serve more efliciently to dash aroundthecontents of the barrel so that the cream will be converted into butter more rapidly. The counter-balancing weight 26 is for the purpose of effecting a more even rotation of the parts, as will be readily apparent.

From the foregoing description and a study of the drawings, it will be apparent that I have thus provided a very simply constructed and easily operated churn which is so formed as to have a combination of movement which will result in producing a more efiicient churning action so as to reduce the time necessary for converting cream into butter.

While I have shown and described the preferred embodiment of the invention it will of course be understood that I reserve the right to make such changes in the form, construction and arrangement of parts as will not depart from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim:

1. A'churn comprising a relatively stationary frame, a frame member journaled within said stationary frame, means for ro 'tating said second named frame, a third frame mounted within said second named frame and connected with the lower por- 'tion thereof at a point spaced from its center, and a churn barrel located within said churn barrel holding frame including a bot tom cross member connected with said second named frame at a point spaced from the lower pivot point thereof, said last named frame further including upwardly extending strips connected at their upper ends, a .hoop member connected with said last named frame, said last named frame being journaled at its center within the upper portion of 'the stationary frame, and

a churn barrel supported within said last named frame and engaged by said hoop.

3. A churn of the character described comprising a relatively stationary upright frame, a gear journaled centrally'of the top of said frame and having an operating handle, a stub shaftdepending from the upper portion of the upright frame, a bevel pinion journaled on said stub shaft and meshing with said bevel "gear, a bar located within said frame and having its upper portion secured to said bevel gear and its lower portion laterally extended toward the center of the stationary frame and journaled at the center-of the bottom of the stationary frame, a barrel supporting frame including a lower cross member, upright strips extending from said cross member, a sleeve connecting the upper ends of said strips and journaled centrally upon said stub shaft below said bevel gear, and a post carried by the lateral extension of said first named bar and secured centrally to said bottom cross member whereby said last named barrel supporting structure will be carried eccentrically of said movable frame structure, and a churn barrel carried within said last named supporting frame.

4. A churn comprising an upright relatively stationary frame, a frame rotatably mounted within said upright frame, means for rotating said second named frame, a third frame mounted within said second named frame and having an eccentric connectionrtherewith, and means associated with said last named frame for detachable engagement with a churn bower whereby to hold the latter within the last named frame.

lnitestimony whereof I affix my signature.

WILLIAM T. MILLER.
